Title: Method and device for producing bags with three sealed edges and welded-in closing seal
Inventor: LOEWENTHAL HORST
IPC: B65B9/067
Filed: 2000-12-01
Granted: 2008-08-05
Abstract: A packaging foil is continuously withdrawn from a supply. The foil is folded around the products to be packaged. Cut-off lengths of closing profile sections are inserted with a feed unit between the two longitudinal edges of the foil. In a sealing station, the two longitudinal edges of the foil are sealed together and the foil is then sealed onto the closing profile sections. In another sealing station, transverse sealing seams are formed between the free ends of successive closing profile sections and the tube is cut approximately in the center of the transverse seams. A high packaging output is achieved as a result of the continuous withdrawal of the foil.

Abstract: A hydroprocessing process for removing impurities from a feed (22) comprising a hydrocarbonaceous liquid comprises at least two cocurrent, upflow hydroprocessing reaction stages (14, 16) and a non-catalytic, vapor-liquid contacting stage (20). The reaction and contacting stages may all be in the same reactor vessel (12). The feed and a hydrogen treat gas (24) are passed up into a catalyst bed which comprises the first reaction stage, which produces a partially hydroprocessed liquid and vapor effluent. This first stage vapor is passed up into the contacting stage (20) in which it contacts a hydrocarbonaceous liquid which reduces the vapor impurity content. The impurity-enriched contacting liquid passes down and mixes with the first stage liquid effluent. The combined effluents and hydrogen are passed up into the second reaction stage to form a processed product liquid and hydrogen-containing vapor effluent. This second stage vapor effluent is passed up into the first stage to provide at least a portion of the hydrogen for the first stage reaction. Additional product liquid may be recovered by cooling and condensing the purified contacting stage vapor effluent.

Abstract: "Plug-in" fluid flow diverters (74) are disclosed. Additionally disclosed is water purification equipment (10) adapted to communicate with the diverters (74). Such equipment (10) is especially (although not solely) useful in connection with circulating streams of water present in systems associated with swimming pools, hot tubs, and spas, as the circulating nature of the water permits more of its volume ultimately to be diverted into the equipmen t for purification. The diverters (74), furthermore, may have entrances orient ed to receive fluid travelling in only one direction through a conduit and be keyed to one or more components of the equipment for purposes of identification, inventory control, or otherwise.

Abstract: Processing of source documents to generate data for indexing, and of queries to generate data for searching, is done in accordance with retrieved tokenization rules and, if desired, retrieved normalization rules. Tokenization rules are used to define exactly what characters (letters, numbers, punctuation characters, etc.) and exactly what patterns of those characters (one or more contiguous characters, every individual character, etc.) comprise indexable and searchable units of data. Normalization rules are used to (potentially) modify the tokens created by the tokenizer in indexing and/or searching operations. Normalization accounts for things such as case- insensitive searching and language-specific nuances in which document authors can use accepted variations in the spelling of words. Query processing must employ the same tokenization and normalization rules as source processing in order for queries to accurately search the databases, and must also employ another set of concordable characters for use in the query language. This set of "reserved" characters includes characters for wildcard searching, quoted strings, field- qualitied searching, range searching and so forth.
